Explanation:

When enabled, prevents domain info being stripped from CC names for users in
the same domain and for users with SMTP addresses.

In R5, when using Reply to All, domain information is stripped from
addresses
in the cc: field for users in the same domain and for users with internet
addresses (due to the presence of the native SMTP router). If you do not want
the domains stripped use this new notes.ini variable to return to R4.6x
behavior.

Applies to:

Workstations

Default Value:

None

UI equivalent:

None, although you can specify this setting in the NOTES.INI Settings tab of
the Configuration Settings document in the Domino Directory.
